Dell today refreshed its line of mobile workstations with the M4600 and M6600, 15.6 and 17.3-inch systems outfitted with Intel's second-generation Core processors, Nvidia Quadro and AMD FirePro graphics, 1080p IPS displays, and, well, just about everything else this side of an Alienware.

Both notebooks will have an aluminum and magnesium-alloy chassis rated to withstand MIL-STD 810G specifications for extreme temperatures, vibration, dust, altitude and shock. The notebooks will be compatible with 1600MHz memory, and can accommodate up to 32GB of RAM (though only using 1333MHz; the max for 1600MHz is 16GB).

Not just for the iPad anymore, an IPS display PremierColor RGB LED display with PremierColor calibration software, capable of 100 percent color, is an option, as is a four-finger multitouch panel, Nvidia Optimus technology, as well as AMD Eyefinity, which supports up to five displays simultaneously.

Both notebooks will also have two USB 3.0 ports, HDMI and DisplayPort, eSATA/USB, and SmartCard and ExpressCard readers. Gobi wireless broadband will also be an option on both.

The M4600 will start at $1,678, and the M6600 will start at $2,158; both will be available on May 10.
